4. FAQ

Q:DO YOU HAVE ANY CERTIFICATION FOR YOUR PRODUCTS？

A:We have ISO9001：2015，CE、RoHS certifications for all of our products.

Q:DO YOU HAVE MOQ FOR PLACE ORDER？

A:Low MOQ，1pe for sample checking is available

Q:How to promote the use of solar energy in China: Overall, the use of solar energy is still very fast, or how the United States will be on China's solar energy products to ban it? As for the overall development of the domestic solar energy industry is good, but still need to do a lot of work. For example, how to improve the quality, efficiency, etc..

Q:What are the disadvantages of traditional solar water heater: Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.

Q:What is the future of solar power: Those who despise misleading consumer advertising! Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

Q:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about: 3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.

Q:Home solar heating products can not mature?: Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time onlineRecommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales

Q:Solar energy products, that is, I would like to open a home solar products Daquan: You come to buy a small brand, I guarantee the same brand and the water temperature. There ah, is to buy low in quality, the water temperature is much higher than the big brands, better quality, but the price is low. This is the answer to the water heater. Now I have to answer your question: I think a large and complete solar business success is unlikely, because you can do fine, because no sales manufacturers will hate you, you will not get a low price, so in the competition you will be in a passive position. There is a large investment in the business field, but this is taboo, because you invested huge output and small, out of proportion. As the election, do fine, do in this field, you are the boss. Others want to see your face. You can make a big profit this time.

Q:The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use: Competitor analysisThe solar water heater industry faces competition and substitute competition, has formed a professional brand, regional brand, brand and brand-name appliances co-exist in the market, the industry has fish, uneven in quality situation. With the competition and homogenization aggravating industry "reshuffle" is inevitable in the competition, need to break through the differences, creating a unique selling point, can focus on the product itself, can also be separated from the product itself, to create new demand from the consumer point of the competition range, consumers in the purchase of solar water heater in the purchase of solar energy is not, but convenient, safe, saving, healthy use of hot water. If you can surround the tube"

Q:Good solar polymer or monocrystalline: Working principle: the light of the sun to the solar battery plate current generated through the inverter controller for battery charging, battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered:

Q:How to make solar energy?: Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.

Q:The steps of making solar technology stubs: Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
